Multi story steel storage buildings are more commonly seen in urban markets with high density populations. Two story storage buildings, or any multi-story self storage building (one, two, three, and four stories) will require alternate access to the upper floors, by means of vertical conveyors (lift) or elevator. Multi-story self storage buildings that are specifically designed for self storage, utilize a load bearing wall system that reduces the structural steel required, making pre-engineered steel storage buildings a great fit for multi story building development. Pre-engineered steel buildings designed for self storage may also include an integrated design for options such as fire suppression systems, solar roofing, increased R-values for wall and roof panels, loading areas, HVAC support, and more. Miller Buildings has decades of experience with multi-story self storage buildings, and pre engineered steel buildings.
